Designation:F1342/F1342M05(Reapproved 2013)1Standard Test Method forProtective Clothing Material Resistance to Puncture1This standard is issued under the fixed designation F1342/F1342M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEDesignation editorially updated in December 2013.1.Scope1.1 This test method determines the puncture resistance of aprotective clothing material specimen by measuring the forcerequired to cause a pointed puncture probe to penetrate throughthe specimen.This test method describes three protocols thatmay be used:Method A,Method B,and Method C.1.1.1 Method A requires the use of Probe A only.The probeused for testing shall be recorded in the test report.1.1.1.1 ProbeAmay be used to measure puncture resistancefor the following types of materials:(1)Elastomeric materials(2)Textiles(3)Coated materials1.1.2 Method B requires the use of Probe B.The probe usedfor testing shall be recorded in the test report.1.1.2.1 Probe B may be used to measure puncture resistancefor the following types of materials:(1)Textiles(2)Coated materialsNOTE1Probe B is not suited for measuring the puncture resistance ofunsupported elastomeric materials.1.2 The values stated in SI units are to be regarded as thestandard.The values in inch-pound units in brackets are forinformation purposes only.The values stated in each systemmay not be exact equivalents;therefore,each system must beused independently of the other,without combining values inany way.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D2582 Test Method for Puncture-Propagation Tear Resis-tance of Plastic Film and Thin SheetingD3767 Practice for RubberMeasurement of Dimensions3.Terminology3.1 Definitions:3.1.1 protectiveclothingmaterial,nanyelement,constituent,or substance from which protective clothing iscomposed or can be made.4.Summary of Test Method4.1 A material specimen is placed in a stationary supportassembly that is in turn affixed to the lower arm of a tensiontesting machine.4.2 A pointed puncture probe of set dimensions is mountedto the test fixture and the whole assembly is attached to thecompression cell of the testing machine.4.3 The puncture probe is moved at a constant velocity untilit punctures the material specimen.4.4 The force required to puncture the material specimen ismeasured by the compression cell.The elongation(or deflec-tion)of the specimen prior to puncture is also measured.Thereported puncture resistance is the average of twelve testreplicates.5.Significance and Use5.1 This test method evaluates puncture resistance of pro-tective clothing materials which may include plastics orelastomeric films,coated fabrics,flexible materials,laminates,or textile materials.5.2 This test method is not intended to measure punctureresistance of all types of punctures encountered using protec-tive clothing material.This test method involves a procedure1This test method is under the jurisdiction ofASTM Committee F23 on PersonalProtective Clothing and Equipment and is the direct responsibility of SubcommitteeF23.20 on Physical.Current edition approved Dec.1,2013.Published December 2013.Originallyapproved in 1991.Last previous edition approved in 2005 as F134205.DOI:10.1520/F1342-05R13.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 where a puncture probe of specified dimensions is used forpuncturing specimens.5.3 This test method evaluates puncture resistance of pro-tective clothing materials,specifically for puncture forced onspecimens perpendicular to material surface.There is nosupporting structure under the material specimen.5.4 Evaluation of puncture resistance for snag-type punctureshould be performed in accordance with Test Method D2582.6.Apparatus6.1 Thickness Gage,suitable for measuring thickness to thenearest 0.01 mm or the nearest 0.001 in.,as specified in TestMethod D3767,shall be used to determine the thickness ofeach protective clothing specimen tested.6.2 Testing Machine,shall meet the following criteria:6.2.1 It shall be capable of holding the specimen securelybetween the two clamps and be capable of straining thespecimen with a uniform movement.6.2.2 A machine capable of providing load versus elonga-tion data until point
